The upper ends of the brackeach end or corner of the screen can be raised 50 ets 0 project above the side frames of the orlowered independently and agreaterorless ICO inclination and jar can be given to the screen on one side than upon the other. This construction enables a finer grade of material to be separated upon one section of the screen at the same time that a coarser grade of material is being separated upon another section of the screen and permits the screen to beadjusted to obtain an even flow and complete separation of the different grades of material acted upon.

2' represents stops secured to the inner side walls of the ease and projecting over the side frames of the screen for limiting the upward movement of the screen and preventing an excessive deflection of the flexible arms.

The material which passes through the screen falls into hoppers J, arranged below the screen, and the tailings are collected in spouts J.

The screen may be kept clear by means of a traveling brush K, which is operated by endless chains or belts K, running over sprocketwheels 70, secured to transverse shafts It. The shaft carrying the lower sprocket-wheels is journaled in movable bearings M, whereby any slack in the chains or belts can be readily taken up and the brush held in contact with the under side of the screen.

The movable bearings M are each provided with an arm or extension m, having an elongated slot m and a projecting lug or shoulder m formed on the under side of the arm. The bearings M are each secured to astationary plate N, which is fastened to the outer side of the case and is provided with an elongated opening arranged in line with the bearing for the passage of the shaft. The plate N is provided with a screw bolt 71, which passes through the elongated slot m in the arm or extension m, and with a threaded lug 0, carrying a set-screw p, which bears against the shoulder or lug m on the arm m. The slot on and set-screw p are arranged parallel or in line with the belt, so that by loosening the bolt a and tightening the set-screw j) the bearing is adjusted and the belt tightened. The bearing M is held from moving vertically by a set-screw *1- engaging in a threaded lug .5, formed in the plate N and bearing against a Hat face formed on one side of the bearing. The set-screw r and lug s are arranged on that. side of the bearing against which the latter is drawn by the movement of the belts or chains.

The cam-shaft g is driven by an endless belt running over a pulley 2, and the traveling brush and feed-roller are driven from the shaft g by an endless chain running over sprocket-wheels mounted on the respective shafts.

\Ve claim as our invention 1. The combination,with the inclined screen and the rotating cams whereby the screen is actuated, of independently-adjnstable wedges which support the corners of the screen and whereby each corner can be raised or lowered, substantially as set forth.

2. The combination,with the inclined screen and the rotating cams whereby the screen is actuated, of supporting-wedges arranged underneath the screen near the corners thereof, and each made independently adjustable lengthwise of the screen, substantially as set forth.

3. The combination, with the stationary frame, of an inclined screen-frame provided on opposite sides witha board or plate arranged above the screen-frame, flexible arms connecting the screen-frame with the stationary frame, rotating cams adapted to strike the under side of the plates for jarring the screen, brackets secured to the stationary frame below the screen-frame, and wedges or inclined blocks adjustably secured to the stationary frame and arranged between the brackets and the under side of the screen-frame, substantially as set forth.

4. The combination, with the screen, the cleaner belt or chain, and its shaft and wheels, of adjustable bearings, each composed of a movable bearing proper M, provided with a longitudinal arm or plate on, and a stationary plate N, on which the bearing M is adjustable and which is provided with an adj usting-screw 1), arranged lengthwise of the belt or chain, and whereby the bearing is moved in the direction in which the belt or chain is tightened, and an ad j usting-screw '1, which is arranged at right angles to the belt or chain and which holds the movable bearing M against the pull of the belt or chain,substantial1y as set forth.
